Title: Method for electrolytically roughening lithographic aluminum substrate
Inventor: NAKANISHI HARUO
IPC: B41N3/03
Filed: 1987-12-18
Abstract: PURPOSE:To obtain a lithographic aluminum substrate hardly staining in a non-printing area and having a high plate wear for a large number of sheets of paper, by a method wherein, a thin layer having a resistance to electrolytic roughening treatment is formed before the electrolytic roughening of an aluminum plate, and then the electrolytic roughening treatment is conducted. CONSTITUTION:A process of forming a thin layer having a resistance to electrolytic roughening on the surface of a cleaned aluminum plate is conducted. As the thin layer, either of an organic film, such as fats and oils, colloidal films and LB film, and an inorganic film, such as oxide films and chemical conversion films, having a relatively high electrically insulating properties can be used. After that, deep pits are generated by an electrolytic roughening treatment. The film is preferably 0.001-0.1g/m<2> thick. If less than 0.001g/m<2>, an effect of forming a deep pit is being reduced. Contrarily, if more than 0.1g/m<2>, the surface has a larger pit diameter, thus being excessively roughened.

Filed: 1998-10-28
Abstract: PROBLEM TO BE SOLVED: To form an image of photographic quality. SOLUTION: Ink is fed from an ink tank through an ink channel coupling the storage tank with an ink jet chamber formed on the first surface of a substrate. The channel has a first end coupled with the storage tank and a second end coupled with an independent inlet passage, and refill each jet chamber with ink. A group of jet chambers in neighboring relationship forms one of a plurality of primitives on the first surface of the substrate and only at most one jet chamber of each primitive is conducted each time. When each jet element of ink jet chamber is conducted, a plurality of ink drops are jetted from the ink jet chamber onto the surface of a medium at one pixel position in one path of the substrate. Until the plurality of ink drops are collided against the medium to be merged, the plurality of ink drops are sustained in substantially separated state.

Filed: 1995-11-17
Abstract: PROBLEM TO BE SOLVED: To reduce the memory capacity used for displaying picture in a picture display device which can be express picture with comparatively less color information and which is suitable for displaying a picture having much same color part. SOLUTION: When picture data is stored, a CPU 1 takes in dots of the picture data from a first line in order, and color of the first one dot is stored in a storage section 10. Color of a dot stored next is compared with color of a right-neighbor dot, if they are the same color, continuous information is stored. Thus, if color of the right-neighbor dot is the same color, continuous information is specified, and if it is different color, color of the dots is stored. When picture data is stored until 16 lines, compression storage of one picture is finished. As the number of continuous color in the same dot is stored, memory capacity can be reduced.
